Introduction to Dijkstra’s Shortest Path Algorithm

WebDijkstra’s Algorithm allows you to calculate the shortest path between one node and every other node in a graph. Algorithm Execution Here’s how the algorithm is implemented: Mark all nodes as unvisited. Mark the initially selected node with the current distance of 0 0 and the rest with infinity. Set the initial node as the current node. WebC++ implementation of Dijkstra's shortest path algorithm Running time: O (E log (V)) Implementation doesn't requere adding all nodes to priority queue in the begining of algorithm.
